GPS coordinates are not updating

I am building app that tracks distance traveled. At the moment, I am having trouble displaying the coordinates. The code runs, but the Distance, which I've set to display the coordinates when Start is clicked, displays 0.00 when clicked.
public class MainActivity extends Activity {
private Button historyButton, startButton, stopButton;
private TextView Distance;
double currentDistance;
private SensorManager sensorManager;
private Chronometer TimeRan;
private LocationManager mLocManager;
private LocationListener location;
double longitude, latitude;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Initializing all buttons and textviews
historyButton = (Button) findViewById(R.id.History);
startButton = (Button) findViewById(R.id.Start);
stopButton = (Button) findViewById(R.id.Stop);
Distance = (TextView) findViewById(R.id.Distance);
TimeRan = (Chronometer) findViewById(R.id.Time_Spent);
mLocManager = (LocationManager) getSystemService(LOCATION_SERVICE);
location = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
currentDistance += .01;
Distance.append("/n " + location.getLongitude() + " " + location.getLatitude());
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(i);
}
};
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode){
case 100:
configureButton();
break;
default:
break;
}
}
public void configureButton(){
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.INTERNET}
,100);
}
return;
}
//Request update every minute or 16 meters
startButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//ignore permission
mLocManager.requestLocationUpdates("gps", 60000, 16, location);
}
});
};
public void GoToHistory(View v) {
Intent history = new Intent(this, History.class);
startActivity(history);
}
protected void EndWorkout(View v){
TimeRan.stop();
//ignore permission
mLocManager.removeUpdates(location);
}
}
Here is my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.stuyk.runningapplication">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".History" />
</application>
</manifest>

locationManager.requestLocationUpdates(
provider,
MINIMUM_TIME_BETWEEN_UPDATES,
MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
new MyLocationListener()
);
You should set MINIMUM_TIME_BETWEEN_UPDATES to time that you want it to be updated frequently and set MINIMUM_DISTANCE_CHANGE_FOR_UPDATES distance the update will change according to your location status.

Android onLocationChanged GPSTracker crashes

I want to send the longitude and latitude from my onLocationChanged method inside the class GPSTracker to GPSPrincipal (Which is my main activity) and activate a toast that shows the longitude and latitude.
I'm having problems with the broadcastreciver to send the data from GPSTracker to GPSPrincipal, also, the aplication crashes and it shows the following error:
FATAL EXCEPTION: main java.lang.NullPointerException at
android.content.ContextWrapper.sendBroadcast(ContextWrapper.java:344)
at
co.edu.javeriana.introcm.gpsexample.GPSTracker.onLocationChanged(GPSTracker.java:192)
The line 192 is:
sendBroadcast(broadcastIntent);
Last line on onLocationChanged inside GPSTracker
GPSPrincipal (Main activity):
public class GPSPrincipal extends Activity {
GPSTracker gps;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gpsprincipal);
}
public void loca(View arg0) {
gps = new GPSTracker(GPSPrincipal.this);
if(gps.canGetLocation()){
TextView latitud = (TextView) findViewById(R.id.showLatitud);
TextView longitud = (TextView) findViewById(R.id.showLongitud);
latitud.setText(String.valueOf(gps.getLatitude()));
longitud.setText(String.valueOf(gps.getLongitude()));}
else {
gps.showSettingsAlert();}
}
public void cambio () {
BroadcastReceiver receiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Located: - \nLat: " + intent.getExtras().get("latitude") + "\nLong: " + intent.getExtras().get("longitude"), Toast.LENGTH_LONG).show();}};
registerReceiver(receiver, new IntentFilter("com.example.broadcast.gps.location_change"));
} }
GPSTracker:
public class GPSTracker extends Service implements LocationListener {
private final Context mContext;
private Location location;
private double latitude; // latitud
private double longitude; // longitud
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context; //Obtener el contexto
getLocation();
}
public void onLocationChanged(Location location) {
Intent broadcastIntent = new Intent("com.example.broadcast.gps.location_change");
broadcastIntent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
broadcastIntent.putExtra("latitude", latitude);
broadcastIntent.putExtra("longitude", longitude);
sendBroadcast(broadcastIntent);
}
Manifest:
package="co.edu.javeriana.introcm.gpsexample"
android:versionCode="1"
android:versionName="1.0">

Potentially seems to be that your context when calling sendBroadcast() is null within the ContextWrapper class. Perhaps you should try using mContext.sendBroadcast and see if that makes a difference.

Trouble with getting location by WI-FI on android

I have a trouble. I can't get location on my HTC incredible.
It's my manifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.locationfinder"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_LOCATION"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity

android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
It's my activity
public class MainActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/* Use the LocationManager class to obtain GPS locations */
LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener mlocListener = new MyLocationListener();
mlocManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 0, 0, mlocListener);
}
/* Class My Location Listener */
public class MyLocationListener implements LocationListener
{
#Override
public void onLocationChanged(Location loc)
{
loc.getLatitude();
loc.getLongitude();
String Text = "My current location is: " +
"Latitude = " + loc.getLatitude() +
"Longitude = " + loc.getLongitude();
Toast.makeText( getApplicationContext(), Text, Toast.LENGTH_SHORT).show();
}
#Override
public void onProviderDisabled(String provider)
{
Toast.makeText( getApplicationContext(), "WIFI Disabled", Toast.LENGTH_SHORT ).show();
}
#Override
public void onProviderEnabled(String provider)
{
Toast.makeText( getApplicationContext(), "WIFI Enabled", Toast.LENGTH_SHORT).show();
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras)
{
Toast.makeText( getApplicationContext(), "snth", Toast.LENGTH_SHORT).show();
}
}/* End of Class MyLocationListener */
}
If I choose LocationManager.GPS_PROVIDER instead LocationManager.NETWORK_PROVIDER and GPS is off it currently makes toast with "GPS disabled". But if I use LocationManager.NETWORK_PROVIDER nothing happens no matter what the WiFi state is.

My location service is not working

My application works as follows:
I have one location listener to every activity
My location listener(which contains location listener) send broadcast on location changed
All activities have broadcast receiver which allows them to set location on map
It has to be working like that, but even my service doesn't start. I'm exhausted writing this app so I place my code here, maybe I overlooked some simple issue. I need help with that topic:

if (current != null) sendSms(data);
else Toast.makeText(getApplicationContext(), "No GPS data yet..", Toast.LENGTH_SHORT).show();
}
break;
}
}
#Override

And to be sure Manifest:

<activity android:name=".RecordTrackActivity" />
<activity android:name=".SettingsActivity" />
<service

</manifest>

The solution is to keep service and activity which uses it in one package.
It is small issue but can be big problem for someone.

Android addProximityAlert does not fire

I tried to implement the addProximityAlert method, but it does not fire. Here is my code:

Sorry I selected not the complete code.

when you add a ProximityAlert you have to pass a PendingIntent to the LocationManager, these PendingIntent will be fired on a broadcastIntent and i dont see in your code when, where you register a receiver for that PendingIntent.
Now a question... why do you write a service if you add the ProximityAlert on an Activity?
